What happens in the Astronomy Tower, stays in the Astronomy Tower

Footsteps on the stairs were tamed by the moans and gasps filling the top of the Astronomy Tower.

A gasp. "I'm sorry guys. Didn't know you were...I'll just," Bill pointed at the exit as his face turned a crimson red.

"Yeah, you leave unless you want me to hex your bollocks into next week," Charlie threatened trying to cover his bare arse. A freckled, white bum that shone under the moonlight, bringing more attention to it than Bill would have wanted.

"Hey, don't threatened me you little--" Bill's angry retort cut by Tonks' seductive purr.

"You don't have to leave Bill. You can join us here," she winked at her boyfriend's brother over Charlie's shoulder.

"Do you want to get hexed?" Charlie asked her indignantly.

"I won't be at the end of your wand and you know it. Now Bill, please stop drooling at Charlie's arse and get over here," she instructed in a tone that left no room for doubt. "Keep going, Charlie. Bill is already catching up and you're ruining the mood with that frown."

Charlie turned to look at Bill with his hand over his crotch, kneeling beside them. "Oh, what the hell...just don't touch my bum!" He continued thrusting in and out of Tonks. "That part is just for my girlfriend to grab," he said between gasps winking at Tonks.
